Expectations of -2 Sportmasters on a Baja
I have a 40 Outlaw with 500 EFI's. Thinking about putting on some -2 Sportmaster lowers. What can I expect? Do I need to change my prop hubs? With they bolt up to my Bravo 1's? Will I gain speed? Will I throw a rooster? Is it worth the money? How much can I get for my stock lowers?
|
What year ? How far are the propshafts below the bottom of the boat? |
I dont think so. Unless you have extension boxes and shorties.
Use the money for cams and heads or whipples. |

2001. Idk measurements... but it's a Baja the x dimension is pretty low in the water.
The extension box gives you leverage and the shorty gets the prop higher out of the water. I dont think shorties by themselves will give you more than 1mph, maybe even net zero if you are lucky, they might even lose speed EVEN if they are shorter. On a 70 MPH boat IMCO lowers will probably slow you down, they did on my boat the first time around. The bravo lowers do much better at these speeds. Bravos give you more bow lift. If you do boxes and shorties you are looking at a minimum of $8000 investment and a LOT of labor and time. Just put the money into heads and cams get real gains. |
^^^^ This. 4-500 Hrs on the boat? Fresh top ends (+ what Keith suggested above if in the budget), go thru ignition system and fuel system. 500EFI Injectors are notorious for many issues, some you do not realize because of the slow degrade in performance over time. Have the injectors tested, flowed and most likely you'll end up replacing a bunch of them.

I was told by someone a while back that the hull will ride too wet no matter what you do, think it needs longer lifting strakes to lift it better, I don’t see the shirties hooking good enough to give it the needed leverage to gain anything, I’m with the guy that said 0 gains or a loss doing it. Getting on plane would be a nightmare I bet too. |

Why would getting on plane be a problem? I dont see that being an issue... maybe I overlooked something. |
Shorter drives make planing harder, bigger props more cavitation .. seems more converned on having a rooster?? Lots of money to see a rooster |

I have zero practical experience with your set up and mods in question, but generally Bajas need that deep prop to get the bow up as they tend to be heavy up front. Drives with deep props also tend to last longer as the prop isn’t beating the water surface. I’ve read time and time again of folks trying every set up on a Baja and generally end up back at factory settings. |

If you want to spray water leave the ladder down and save the 8 grand

I was told from one of the Baja builders that they copied the hull design from the straight bottom 38 Top Gun, and stretched it 2 feet for triple engine options. So... I beg to differ that it wouldn't benefit from mods. Although, Baja Rooster makes a good point... Baja set these boats up correct from the factory... so I'd prolly be back at square one eventually.
Still curious of real world experiences, because the cost for just -2 shorties is minimal. If I saw any gains... other than cool looking nose cones... it could be worth it. |
If you were running 700-800 a side and running well over 80 you might pick up 1-2 mph but not with your power

The 40 is a stretched 36 Baja, the 36 baja STARTED as a old Squatron mold and changed around, the 40 rides wet due to lifting strakes not being right, I am friends with the person who designed the baja 40, my info on the 40 is accurate. not a top gun mold at all or ever.

I would say that’s going to depend on what your goals are ? I’m not saying it can’t go faster but it’s going to take a considerable mount of money to see something worthwhile, as far as if it’s worth it or not that’s up to you and how much money you want to spend. I spent $50,000 to gain two or 3 miles an hour on my mistress because the boat was set up simply to not be fast. |
Here’s my opinion after the adventures I’ve done for the last 10 years if you actually want to go fast buy a fountain or a hustler , if you want a true rough water boat buy a Apache a cigarette or Pantera ... if you want a cheaper all around fun boat that does A little bit of everything by a Baja |

Put your money towards better trailer tires . Youll need ALOT more power to get that old hull moving

Have you had the boat out yet, whats it running the way it is.

Of course it is. It’s just the consensus of experience is that the direction of where you want to put the money will return little if any gains. You asked what could be expected with such mods and the brain trust has spoken. I’ve personally have spent more time and money going backwards than I would ever admit to my better half. ;p |

If your looking for extension boxes / drives I’ve got both I’m looking to get rid of. Hydraulic steering and props aswell would love to sell as a package deal PM me |
